Measurement and Processing of Thermographic Data of Passing Persons for Epidemiological Purposes.

Non-contact temperature measurement of persons during an epidemic is the most preferred measurement option because of the safety of personnel and minimal possibility of spreading infection. The use of infrared (IR) sensors to monitor building entrances for infected persons has seen a major boom between 2020 and 2022 due to the COVID-19 epidemic, but with questionable results. This article does not deal with the precise determination of the temperature of an individual person but focuses on the possibility of using infrared cameras for monitoring the health of the population. The aim is to use large amounts of infrared data from many locations to provide information to epidemiologists so they can have better information about potential outbreaks. This paper focuses on the long-term monitoring of the temperature of passing persons inside public buildings and the search for the most appropriate tools for this purpose and is intended as the first step towards creating a useful tool for epidemiologists. As a classical approach, the identification of persons based on their characteristic temperature values over time throughout the day is used. These results are compared with the results of a method using artificial intelligence (AI) to evaluate temperature from simultaneously acquired infrared images. The advantages and disadvantages of both methods are discussed.

Contactless Temperature Detection of Multiple People and Detection of Possible Corona Virus Affected Persons Using AI Enabled IR Sensor Camera

Today our whole world is entangled with the most dreadful disease Corona which is caused by the successor of SARS known as SARS-Cov-2 virus. Coronavirus is the influenza-like respiratory disease causing damage to the respiratory system of the humans through the ACE2 receptors which acts as an entry gate for the virus to enter. The Corona virus was identified in late 2019 in the city of Wuhan, China which later spread to the most of the territories in China. The spread was first identified by the Bluedot which is a Saas service designed to track and detect the spread of infectious disease. When the other countries came to know the severity of the virus they made various steps to prevent the spread of the virus. The initial symptoms of coronavirus are rise in temperature, loss of taste and smell and short breathness. As the entry level check many institutions and offices, checks the body temperature of the people and checks whether the person is wearing a mask or not. To make this process fully automatic without human intervention the use of AI enabled IR camera sensor with the Arduino UNO is made. The detection of temperature can be made possible by the use of the computer leveraging vision techniques which is equipped with the Raspberry-pi camera module. The process is based on the thermal imaging of the person which can detect the elevated temperature of the person and prevents them from entering into the institution or offices thereby the spread due to the possibly affected persons can be avoided thereby the spread can be controlled. The system not only identifies the person with high temperature but also checks whether the person is wearing a mask or not. The real time analysis of the system is the major advantage of the proposed system.
